Final answer:
Stephanie spends 312 minutes in class per day, calculated by multiplying 6 classes by 52 minutes per class. The options provided in the question are incorrect.
Step-by-step explanation:
Stephanie's total time spent in class per day can be calculated by multiplying the number of classes she has by the duration of each class. Since she has 6 classes, each 52 minutes long, we perform the calculation:
6 classes × 52 minutes per class = 312 minutes
Therefore, Stephanie spends a total of 312 minutes in class per day. None of the provided options (a to d) are correct as they either provide a vastly exaggerated number or an incorrect unit of measurement (hours instead of minutes).
